It just was not documented before, or supported by the driver. I have sent a patch to document the fourth interrupt[1]. Once that patch has been applied, adding support for sh7751 involves adding just two new lines.

Add SH7750 TMU entry. I wanted to replace interrupts and interrupt-names in the if compatible is "renesas,tmu-7750", but it seems that I can't rewrite it as expected. This resulted in a redundant conditional statement.
